Answer:
1. Grassland ecosystem has high biodiversity.
An aquatic ecosystem has low biodiversity.
2.The biotic components of the grassland ecosystems are producers, consumers, and decomposers. Aquatic ecosystems have five biotic or living factors: producers, consumers, herbivores, carnivores, omnivores, and decomposers.
3.Mutualism-both organisms are benefited from each other. No one is harmed. Commensalism-one organism is benefited but the other is not and unharmed.
Predation-this relationship involves predator and prey. Prey is harmed and eaten while the predator is benefited.
4.High biodiversity, with many species present, is good. It usually means that an ecosystem is healthy and relatively undisturbed by humans.
5.Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play.
